This invention relates to ordnance of the I kind having means whereby the guncan be 7 depressed to a Convenient angle for. loading without,disturbing the sights, the said tween which and the gun cradle suitable means comprising a pivoted member begearing (termed the elevating loading gear) isdisposed and which is displaced by -the elevating gear to elevate the. gun and the sights together; the portions of the said member that are contiguous to its pivotal axis are disposed between the gun cradle and the carriage side cheeks. The invention is particularly applicable to naval guns'of the casemate or upper deck type, but it may also be employed in connectionwith guns other than 'thosemounted on ships. I 7

According to the. present invention the aforesaid pivoted member comprises a stirrup piece which passes under the gun cradle.v and is looselymounted 'uponthe portions of the gun cradle trunnions: that, are situated I between the cradle and'lthefcarriage side 1 cheeks in which thelsaid trunnions arepi v oted.

In order that thelsaid invention may f clearly understood and readily carried-into effect, we willdescribethesamemore fully side showing a constructional form ofiour' invention.
